Angiostrongylus vasorum is endemic in foxes and other carnivores in the South and south East of France, Denmark and Great Britain. The reddish nematode is present in the Arteria pulmonalis and the right side of the heart and causes respiratory and cardiovascular symptoms. From 1999 to 2004, A. vasorum was diagnosed in 5 dogs from northern Switzerland, in 1 dog from southern Germany and in 3 dogs from south Ticino. Clinical signs in the affected dogs varied and ranged from cough, tachypnoea and dyspnoea to neurological symptoms in 2 of the dogs. Four dogs died and in 3 of the 4 dogs adults and larvae were found after digestion of formalin-fixed tissue. Diagnosis in the other 5 dogs was achieved by detecting the larvae coproscopically. Based on anamnestic data, these 9 dogs are probably autochthonous cases.
